This invention relates to paper dispensers and particularly to apparatusof this character for dispensing a measured length of paper.

In cylinder printing presses the pad of the bed 5 roll is provided withan outer cover of oiled paper or the like. In applying the oiled paperto the bed roll the free end thereof is inserted in an opening or slotprovided between the semi-cylindrical bed roll sections which may bemoved away from each other to receive the end of the paper and thenbrought together so as to clamp the end of the paper in position. Theoiled cover paper is quite expensive and heretofore there have been nomeans for accurately dispensing the desired length of paper and forturning down the desired size ap or margin which is inserted in the slotin the bed roll. It will be appreciated that in rolls of differentlengths a different size strip of paper must be dispensed. It will alsobe appreciated that the ap or margin must be accurately measured andmust be formed at right angles to the lateral edges of the pages.Heretofore a length of paper was dispensed and then it was trimmed tothe desired size, with the result that there was considerable waste ofpaper. Also the accurate measurement and folding of the flap resulted inWasting a considerable amount of time.

It is an object of this invention to overcome the difficultiesvheretofore encountered and to provide an improved paper dispenserparticularly suited for dispensing a predetermined measured length ofpaper and for providing the strip of paper with a marginal crease spaceda predetermined distance from one edge of the strip and disposed atright angles to two of the edges thereof.

A further object is the provision of an improved paper dispenser of theabove character in which the measured amount of paper that is dispensedthereby and also the spacing of the crease from the edge of the stripmay be readily varied so as to adapt the dispensed paper to bed rolls ofvarious sizes.

For a fuller understanding of the invention reference should be had tothe accompanying drawings, in which Figure l is a side View of a paperdispenser embodying my invention;

Fig. 6 is a perspective view of the end oi the dispensed paper showingthe manner in which the marginal flap is turned down; and

Fig. 7 is a perspective view showing the dispensed paper formed into acylinder in the manner that it is applied to the bed roll of thecylinder printing press.

My paper dispenser consists primarily of a pair of feed rolls I and IImounted on shafts I2 and I3 which are suitably journaled in the bracketsor uprights I4 and adapted to feed or dispense paper from the supplyroll l mounted upon the shaft I6 which is supported adjacent its twoends in slots I'I formed in the brackets I4 beneath the feed rolls I0and II. The feed rolls I 0 and I I are preferably provided with aperipheral coating indicated at I8, formed of some suitable yieldingresilient material such as rubber, so as to increase the frictionalengagement and to insure positive feeding of the paper. The rollers aredisposed in relatively tight engagement so that rotation of one willcause rotation of the other and likewise will cause feeding of a stripof paper projected between the rolls. I provide suitable means forrotating the rolls, preferably in the form of a crank or handle I9secured to the end of the shaft I2 of the lower roll on the outside ofone of the brackets I4.

It will be seen that due to the fact that shaft IB on supply roll I5 ismounted in the end of slot Il the supply roll can be readily andconveniently inserted in the brackets and removed therefrom. A roll ofthe desired type of paper should be inserted as shownand the end of thepaper fed upwardly between the feed rolls I Il and II. As stated, mypaper dispenser is particularly suited for dispensing heavy oiled paperor the like to be used as a protective coating on the bed roll of acylinder printing press, and accordingly a roll of paper of thischaracter is preferably inserted in the device.

So as to provide for a depending flap or margin of the desiredpredetermined width my apparatus preferably includes a creasing disk orrcller, indicated at 20, mounted on shaft ZI, which in turn is carriedby the arm or bracket 22, The creasing disk or roller 20 engages feedroll I Il at a point in the paper feed prior to roll II. The peripheryof the creasing disk or roller is preferably tapered as shown mostclearly in Fig. 5 and it presses against feed I0 so as to impart acrease in the paper being fed therebetween as shown most clearly at 23in Fig. 4.

For different bed rolls it is desirable to have margins or iiaps ofvarying width and for this reason I provide the creasing disk or rollerwith an adjustable mounting in the form of a collar formed at the end ofthe bracket 22 and disposed around the horizontal adjusting shaft 2l!which is preferably provided with graduations 25 as shown, so as toindicate the spacing of the crease from the edge of the paper. It willbe appreciated that the creasing disk or roller may be adjusted alongshaft 24 so as to provide a marginal flap of the desired width, and inorder to retain the creasing disk or roller in the desired adjustedposition I preferably provide a set screw 26 in the bracket 22, which isadapted toengage the shaft 24.

I also provide my improved paper dispenser with suitable means forindicating and limiting the length of the strip of paper dispensedthereby. This means preferably takes the form of a geared disk 21 ofrelatively large diameter mounted upon stubI shaft 28 which is` engagedand operated by the relatively small pinion 29 carried by shaft I2 ofroller It! adjacent the handle I9. Formed around the disk at regularlyspaced intervals adjacent the periphery thereof are a series ofapertures 30 adapted tol receive a removable pin 3| which engages thestop 32 when it reaches the top of its path of rotation so as to limitthe operation of the paper feed when the disk 21 has been rotated apredetermined distance. It will be seen that the stop 32 is secured tothe bracket I4 beneath the disk 21 and in registry with the openings 33when they are positioned adjacent the top of the disk, and isaccordingly in the path of movement of the pin 3| when it is protrudedthrough one of the openings 30. The distance between apertures 3B isuniform with the result that rotation of handle I9 a suicient distanceto cause rotation of disk 2| for the distance between two adjacentapertures will result in the dispensing of a uniform predeterminedlength of paper. When the handle I9 is turned in a clockwise directionas viewed in Fig, l it will cause the paper to feed outwardly from thefeed rollers and will also cause the disk 21 to rotate in acounter-clockwise direction in the direction of the arrow in Fig. l.Before turning the crank I9 the pin v3| is placed in one of theapertures 353 the desired distance from stop 32 so that the handle I9may be rotated to dispense the desired length of paper. The handle I9 isthen turned until the pin 3| engages stop 32. The operator will thenknow that the desired amount of paper has been dispensed.

So as to facilitate severing the dispensed predetermined length of paperfrom the strip of paper I preferably provide a cutting device 33 in theform of an inverted U-shaped channel member 34 serving as a` platen andan inverted U-shaped channel member 35 spaced from and positioned abovethe platen 34 as shown. The strip of paper is threaded between themembers 35 and 34| and it will be observed that when the paper isdispensed by the rollers it will be fed through the cutting device asshown.

In using my device the creasing disk or roll is adjusted along shaft 35to provide a margin or flap of the desired width. The supply roll I ofthe desired type of paper is then placed in the brackets I4 and thepaper strip is fed upwardly between the creasing roll 2D and feed rollIIE, between the feed rolls IIJ and II and thence through the cuttingdevices 33. The leading edge of the strip of paper is then severed atthe cutting device by tearing the paper along the straight edge at theforward end of the device. Pin 3| is then placed in the aperture 30which will provide for dispensing of the desired predetermined length ofpaper. Crank I9 is then rotated in a clockwise direction as viewed inFig. 1 with the result that the paper is fed between the rolls andthence outwardly through the cutting device, When the pin 3| engages thestop 32 it will be appreciated that the desired predetermined length ofpaper has been dispensed. The paper is then severed by tearing it alongthe straight edge of the cutting device. The dispensed length of paperwhich is indicated by the numeral 31 is then folded along the creaseline 23 to produce the marginal flap 38. The flap is then inserted inthe slot or opening in the bed roll of the cylinder printing press, andthe paper rolled transversely of the strip around the roll as shown inFig. 7. To dispense an additional length of paper the pin 3| is againplaced the proper distance from stop 32 and the handle I9 is turneduntil the pin engages the stop. Where the paper is to be used with bedrolls of different axial lengths the spacing of pin 3| from stop 32 sVaried accordingly. The width of the margin or flap 38 may also bevaried to suit the particular bed roll.

To facilitate adjustment of the paper feed so as to feed the desiredpredetermined length of paper the bracket I4 may be calibrated aroundthe periphery of disk 21 so as to indicate the length of paper that willbe fed if the pin is inserted in the aperture 30 positioned nearest thecalibration or marking.

From the foregoing it will be appreciated that I have provided animproved paper dispenser particularly suited for dispensing paper to beused as a protective cover for a bed roll of a cylinder printing pressand which may be adjusted to dispense any desired predetermined lengthof paper and to form a crease at the desired predetermined distance fromone of the edges of the paper.

It should be understood that modifications may be made in theillustrated and described embodiment of my invention without departingfrom the invention as set forth in the accompanying claim.
